One thing you might try is, if your video card software allows, match your anti-aliasing settings with the setting in galciv's options screen. So if galciv is set to 4X antialiasing, then go out to your card software and set it from "application controlled" or whatever its on to 4X. It can be anything, just make sure they match, and you are running 32 bit color in 1024x768 resolution, and you have latest drivers, directX, etc. I reccomend latest soundcard drivers as well.
